Why do two people get the same (or almost the same report) although they have answered differently in the questionnaire?

In the questionnaire, there are 12 possible combinations in each question. Since there are 24 questions (with 12 possible combinations in each) the total number of possible ways to answer the questionnaire is 79 496 847 203 390 800 000 000 000! Managing that many different combinations would be both totally impossible and meaningless. Hence, the number of combinations has been reduced into combinations that have internal resemblance that is greater than external (i.e. they resemble each other more than combinations outside the group). Note! There is no interpretational information in the individual answers. The answer can only be used for the next step in the process. Answers of two or more individuals can not be compared to one another. Calculating the Profiles and the Diamond. The process for calculating the Profiles is a combination of straight-forward mathematical equations that reduce the number of combinations to 11 753 582 400. Managing that many different Profiles would still be impossible and the differences in the Profiles would not represent significant differences in the individuals’ actual behaviour.

To help the Extended DISC user utilise the Profiles, a classification system with different levels of deepness has been created:

Level Differentiating feature

Number of combinations
1 Dominant character
(example: I)
4

2 Letter combinations
(example: ISC)
40

3 Upper Percentages
(example: 0-50-30- 20)
800

4 Lower Percentages
(example: 100-0-0- 0)
n/a

The different levels are used for different purposes. In general training, Level 1 is often deep enough. In applied training (like sales training) Level 2 is often appropriate. In that case, every 40th person on average gets the same result (Profile combination).
